you there ?

Expert:  Dr. Dan replied 3 years ago.
Hmm adam, if nothing is coming up except a slash, it sounds like the boot sequence is having a hard time finding OSX and could suggest a boot failure possibly due to a hard drive failure. Are you getting any beeps or anything else? Do you know the model number of your Macbook and what OS you are running?
Customer: replied 3 years ago.

yeah i think its the osx the mac cant find and the os i run is osx.. the model is 13 inch mid 2009

i was locked out of my laptop and he told me to get a keyboard because the keys for the mac were malfunctioning.....i'm thinking i probably erased it mistakenly

Try seeing if your Macbook will start in safe mode:

What is "Safe Mode"?

Safe Mode is a way to start up your Mac that performs certain checks and prevents certain software from automatically loading or opening.

Starting up in Safe Mode does several things:

It forces a check of the startup volume, just like the First Aid feature of Disk Utility. You may see a progress bar on the screen during this check, and the computer takes longer than usual to complete its startup.
It loads only required kernel extensions.
It disables all fonts installed by the user.
It moves font caches to the Trash that are stored in /Library/Caches/ – where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later).
It disables all startup items and login items in Mac OS X v10.4 or later.
In Mac OS X v10.3.9 or earlier, Safe Mode opens only Apple-installed startup items (such items may be installed either in /Library/StartupItems or in /System/Library/StartupItems). These items are different from user-selected account login items.
Taken together, these changes can help resolve or isolate certain issues that exist on the startup volume.

Starting up in Safe Mode

To start up into Safe Mode (to Safe Boot), follow these steps.

Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.

To leave Safe Mode, restart your computer without holding any keys during startup.

i tried safe mode but it still goes back to the slash line

Hmm, at this point this may need servicing or diagnostics with Apple, do you have a Apple store near you where you can have it evaluated? Otherwise I would recommend contacting Apple UK support:

Sounds like there may be a hardware failure which is preventing you from booting.
